te/ti in termcap(5) language.  rmcup/smcup is the same in terminfo(5).

That's not what happened.  The ti/te capabilities for switching to
the alternate screen were expressly removed from the "xterm" entry
in revision 200503, because a vocal group of developers disliked
the alternate screen feature and insisted that it should be disabled
in xterm.
